Detailed Answer
Answer (C) is correct.
In consolidated financial statements, the effects of intraentity transactions
should be eliminated. The original amount recorded for the acquisition
by Water Co. of the equipment from Fire Co. was the carrying amount on
Fire’s balance sheet plus the gain on the sale. In the consolidated financial statements, the equipment should be reported at the amount previously recorded on Fire’s balance sheet. This amount is the original
cost recorded by Water minus the gain recognized by Fire when the
transaction took place.
